, This invention relates to new and useful im rovementsinpropellers.

ne object of theinvention is to provide an im roved pro eller device employing a [3) plurality of individual propelling units seg" regated so that each unit individuallysuppiles itself with fluid and expels said fluid in an individual strata, thus amplifyingthe propelling power of the device.

v,10 A furtherobject of the invention is to rovide a propeller of the type set forth, which may be utilizedin'any position found praco tical, such as for lifting, or moving in a horizontal plane, or for pulling downwardly, and

.1 usable in'any fluid, such as air, water, gas

or the like.

Another object of the invention is to provid'ea propeller device including a lurality of superposed planes or wings arr form:

v ing propeller stages havin propellers therein together with conduits or supplying each stage with the fluid in which the device is used, whereb the supplied fluid is propelled radially of t e stages and discharged there? -from against the surrounding fluid stratas, thus making for more eflicient propulsion.

A still further, object of the invention is to provide a propeller device including a plu rality of superposed planes or wings ofv 01- ,30 low construction and each being air tight exceptingfor a suitable opening, whereby individual propellers coactin with the opening'in each plane tend to raw ojut the-air through said opening and ,thus find to en 851hance the huoyancyof the device.

' A construction designed to carry out the invention will be hereinafter described tos geth er with other'features of the invention.

The invention will be more readilyund'er- .40 stood from a reading of the following specification and by reference to the accompany ing drawings in which an exampleof the invention is shown, and wherein:

Figure 5 is a detail of the fluid conduits. In the drawings the numeral 10 designates" a support or frame which comprises an upper s ider 11, a lower spider 12, posts 13, and

at the topcenter of the upper spider and the spider 12extends from a lower bar 16. I

'' A p'lurality'of concavo-convex planes or wingsA, B, C and D are mounted in the frame-andbetween the'spiders. ;The posts 60 j "13 and the standards 14 penetrate these planes, except that the posts 13 do not extend through the lowerjplane D, but said lane'is secured at its outer edge to said posts y eyebolts 17. The lanesfA, B,' and C,

' respectively, are carrier? by spreader wings 18 and 19 which are fastened onlthe posts 13) and the standards 14 respectively. The upper plane A is of single thickness, while the remaining planes are hollow and of double thickness. These planes may be made of any suitable material, such as sheet metal or an equivalent v vAn'axi l driving-shaft 20 extends through the bearingunember 16 and terminates in the 75 hearing member 15, which forms a thrust bearing; Prop elling stages are formed between the planes and these planesare preferably concentric and'are spaced apart sufficiently to receive propellers" 21 the'rebetween, which retatein'said stages, In order V to provide snug operating spaces for the re ,ellers, the central portion of each plane E, (l and I). is flattened so as to. provide upper I and-lower disk ortions 22. The propellers are fastened to t e shaft QOby bolts 23. 3

Concentric cylindrical "conduits A -l,

A-2, and A-3 are disposed concentrically around the shaft 20 within the spider-11 and between the pdsts 14. The outer conduit A--1 has-itsouter end within the standards 14 and its inner end terminates at the. under side of the top plane A, as is shown in Figure 3.

The ends of the conduits are stepped and the inner end of the conduit A-2 terminates at 95 the under side of the plane B, while the inner end of the-conduit A--3 terminates at the underside of the plane O. The propellers extend through the conduits A--2and A--3.'

stan ards 14. A hearingcap 15 is carried Spiral baflies 25 are arranged-in each conduit and as each conduit supplies fluids to an individual propeller 21, which fluids are drawn in by said propellers; it isobvious that the baflles will impart a whirling motion to these fluids. The propellers are given a sinuous shape in plan, as is shown in Figure 4, and rotate in a clockwise direction so that the fluids are thrown outward in the stages between the planes. These fluids striking the curved surfaces of the planes are discharged from said planes in streams, thus giving adequate propulsion. l

Where the propeller device is used on.airplanes or other devices in which the fluid is air, the device may be arranged vertically for lifting, or it may be arranged horizontally for pulling. The impact and displacement resulting from the discharge of the streams from the plane stages, together with the shape of the planes will give a superior propulsion; The same is true where the device is used in water, in which instance it could be used on the bottom or the top, or the side or the end of a vessel, as is obvious. I

In order to add to the buoyancy of the device the planes B, C and D have openings 26 in their upper sides located so that the ends of the propellers pass over said openings, as is indicated in Figure 3. The planes being otherwise fluid tight the rapidly rotating propellers will tend to draw the fluids out of the hollow planes and thus tend to'create a vacuum therein, which will thereby increase the buoyancy of the device.
